Sorry for that, my english isn't as good as i'd like
the program that i'm trying to install is dc (dc-0.2.19.tar.gz, a direct connect client that can be found on
http://download.berlios.de/dcgui/dc-0.2.19.tar.gz) and it is composed by its librarys and a gui. When executing the ./configure of the gui, it tells me the follow:
...
checking for libpng... -lpng -lz -lm
checking for libjpeg6b... no
checking for libjpeg... -ljpeg
checking for Qt... configure: error: Qt (>= Qt 3.0) (headers and libraries) not found. Please check your installation!
...
I didn't known about qt-devel, I'll try to install them. I thought that maybe the problem could be some enviroment variables. Thanks for answering
